Last week, Green, 46, said a detective brought a replacement ticket to his house and told him "something was wrong with their computer system." The investigator also asked whether Green called Assistant Chief Luke Williams to complain about the ticket, Green said.

"Luke had nothing to do with the ticket," Green said. "I never called Luke. I don't know what they're trying to drag me into. I'm paying the ticket next week. This is ridiculous."

Green said he took offense to the detective calling several times for a meeting even as he planned his mother's funeral.

Police spokesman Bill Proffitt confirmed the "ongoing investigation," but said he "cannot discuss specifics or give any further comment" until the inquiry ends.

Interim police Chief Dave DeKay said Wednesday that Williams is not a target of the investigation.

Departmental politics could be playing a role. Williams is one of the top internal candidates vying to be the next police chief. He doesn't know why his name surfaced.
